Description

Features

Test Frame

• The twin-column OmniTest features dual circulating ballscrews that drive a solid crosshead onto which is mounted an ELS loadcell. Excellent rigidity and strength with intuitive controls make the tester easy to use even for novice operators.
• The robust design of these twin-column testers delivers the strength capability for high-load break tests on rigid materials whilst providing ample space between the columns for mounting larger specimens that cannot easily be accommodated on single-column test frames. Their extensive crosshead travel also makes them perfect for low-force, high-elongation tests up to 1230mm. All models are ideal for the universal testing of samples to determine their tension, compression, flexure, shear and fracture characteristics.
• Upper and lower safety limit switches minimize the risk of accidental damage caused by grips colliding. The test frames also feature a protective bellows to prevent dust and splintered materials from becoming trapped inside the machine.
• For operator safety a range of protective shields and enclosures is available, for situations where specimens may shatter or create projectiles upon failure.
• Designed to apply tensile and compressive forces up to a capacity of 50 kN their high-quality construction, manufactured under ISO 9001 quality standards, ensures the ultimate in repeatable materials and product testing.

Loadcells

• The OmniTest UTMs take advantage of Mecmesin’s range of high-resolution Enhanced Load Sensors (ELS) to record tensile and compressive loads. These interchangeable loadcells are compatible with any test frame of equal or higher capacity, in order to optimize the accuracy of your test results.
• The ELS range of high-resolution, precision loadcells is specially adapted to the OmniTest. They are fully interchangeable and plug into the frame, where their calibration characteristics are immediately recognized by the tester without any input from the operator.
• Twenty-five different sensors, all measuring from zero, are available to cover the range from 2 N up to 50 kN. This ensures that you have the optimum selection to meet all your tension and compression testing needs. Measurement accuracy is an outstanding ±0.5% of displayed reading.
• Each ELS sensor is delivered as standard with its own calibration certificate traceable to national standards.
  • CSC can provide an ISO17025 calibration cert.

Software

• VectorPro delivers outstanding control of the motor, whilst simultaneously collecting data at 500 Hz from the ELS loadcell and the displacement encoder of the frame.
• The software is intuitive for both operators and managers. Personalized user accounts and a streamlined design mean that the workflow is simple and it is easy to create step-by-step test methods according to the precise requirements of your testing procedures.
• Access to the most commonly used test methods enables operators to move seamlessly from task to task and keeps training time to a minimum.
• By plotting the data of force/displacement, stress/strain in real-time on a graph the operator can immediately identify exactly how the test sample is performing. Preset or custom calculations analyze the data to determine whether the specimen has met the pass/fail criteria.
• VectorPro includes standard calculations for Young’s Modulus, Offset Yield, Ultimate Tensile Strength, Nominal Strain and a whole host of other materials characteristics.
• For product testing, it is possible to create custom calculations within a few seconds by using the drag-and-drop functions.
• At the end of the test, the comprehensive reporting module within VectorPro enables the operator to issue a test report as a PDF.
• An extensive suite of template reports can be easily tailored to your internal or your customer’s exact requirements and be automatically emailed to them as an HTML file. Test data can also be exported to Excel or to the network for further analysis.
• VectorPro generates a clear audit trail with electronic-signature functionality – a must for medical and pharmaceutical clients seeking compliance to FDA 21 CFR Part 11.

Grips and Fixtures

• Holding your test specimen in place without it slipping is essential to obtaining repeatable results. Mecmesin has designed a range of tension and compression grips to hold a variety of components. They include wedge grips, vice grips, peel jigs, bend jigs, compression plates and many more.
• The base plate of the OmniTest is pre-drilled with threaded holes to connect a wide range of grips and fixtures. The OmniTest also uses quick-change (QC) adapters that speed up the interchange of grips when you need to perform a variety of different tests.

Extensometry

• When testing the extension or compressive deformation of a specimen it is often acceptable to measure the movement of the loadcell and grips, as defined by the crosshead distance traveled (known as ‘Grip Separation’).
• This is taken directly from encoders situated on the ballscrews of the OmniTest. VectorPro software compensates for movement encountered within the loadcell and grip string (known also as ‘Correction for Machine Compliance’) but it cannot be as accurate as measuring extension directly upon the specimen. In some test applications, this is perfectly acceptable and does not impact the relevance of the measured results.
• For materials requiring extension measurement to be taken directly on the specimen, a range of contact extensometers is available for use with the OmniTest. The range of contact extensometers include short-travel extensometers suitable for rigid materials (eg hard plastics and metals) through to long-travel extensometers designed for highly elastic materials (eg rubbers or soft plastics), simply select the model which best suits your material’s characteristics

Safety Guard

• Our systems can be supplied with a standard safety guard to prevent access by the operator to the testing area whilst the test is in progress. These have a rigid metal frame with integrated poly carbonate panels to allow the operator to view the test area from outside. Hinged doors are fitted with switch-activated interlock mechanisms that prevent system operation when open.
• Guards for twin-column test stands are supplied with new equipment and are pre-fitted to the tester at our factory, all ready for use when unpacked and installed.

Specifications

• Accuracy
  • When calibrated as part of a system, accuracy is ±0.5% of reading down to 2% of range, suitable for use with Class 0.5 systems according to the requirements of ISO 7500-1. Eg, ELS 100 when measuring 10N is accurate to ± 0.05 N or when measuring 50N it is accurate to ± 0.25 N.
